BENCH-CLAMP.

SPECIFICATION forming part of Letters Patent No. 322,434, dated July 21,1885.

To @ZZ whom t may concern:

Beit known that I, HIRAMC FENTON, of Hartford, in the county of Hartfordand State of Connecticut, have invented certain new and usefulImprovements in Bench-Clamps, of which the following is a description,reference being had to the accompanying drawings, where- Figure 1 is abottom view of my improved clamp. Fig. 2 is a side View of the same,shown 'as attached to a bench. Fig. 3 is a view in horizontal sectionthrough the clamp on plane denoted by line a: x of Fig 2.

The object of my invention is to provide a bench-clamp of simple andcheap construction adapted to be secured to the under side of a bench,seat, or like structure, for firmly holding a removable tool or thelike; and my improvement consists in the body or holder of the clamp,cast to shape, with a tool-socket extending completely through it, and asecond socket within the body and crossing the first, in which islocated a movable clamping-arm bearing means for operating it, as moreparticularly hereinafter described.

. In the accompanying drawings, the letter a denotes the body of theclamp, preferably made of metal, cast to shape, with the anges a a2,projecting from the sides of the body near and in the plane of its side,adapted to rest against the structure to which it is to bel secured, andthrough these anges are scrcwholes, whose use is obvious. At rightangles to the bearing-surface of the body is a perforation, Z),preferably cylindrical, and at about the center of the body is atransverse clampesocket, c, with the narrow part c adapted to containthe broader part of the clamp d, while the stem d extends past the holeb and projects sufficiently beyond the farther side of the body a asto-afford space for supporting the lever e. This levers is pivoted uponthe stem of the clamp, and held against outward play on it by means vofa nutor like device, and it bears on the face next to the body of theclamp one or more cams, e', that (zo-operate with cams e2 formedupon thebody of the clamp, which cams are so Application filed J une 1. 1885.

arranged that by depressing the lever the grasping-face d2 of thehooked' arm of the clamp is pulled toward the hole 11 in such manner asto firmly grasp the stem or spindle f of any tool that may be thrustthrough the hole.

This clamp as a whole is adapted to be secured to the under side of abench or like structureA so that the hole b registers with a holethrough the bench, so that the Shanks of a benchhook or other tool thatis to be used upon the upper surface of the bench may be thrust throughthe hole into the body of the clamp, and held firmly by means of theclamping-lever already described, it being understood that the shank ofvsuch tool or the handle of the article'shall be of a size adapted tofit quite closely within the hole bin the body ofthe clamp.

This clampbody,with its respective flanges, openings, and cams, isformedin a single easting, and the clamp is inclosed Wholly within the body ofthe structure.

I am aware that similar clamp devices, having parts adapted to bebrought together forcibly by means of a lever bearing camfaces, are notnew, and such I do not, broadly, claim.

I claim as my inventionl. In combination with the clamp body a, havinganges a a, vertical socket 1),' and transverse cla1npsocket c and thecams, all cast in one piece, the hooleshaped clamp d, located within theclamp-socket c, with its broader part bearing the grasping-face cl2 andits stern d bearing the cam-lever e, all substantially as described.

2. In combination with the clamp-body a, having the vertical socket b,the transverse clamp-socket c, opening into the other and bearing on anouter side the cams c2, the hook- -shaped clamp d,located within theclampsocket, with its broader part having the grasping-face d2 and itsstem d bearing the cam-lever e, all substantially as described.
